7h all whom'it may concern.

Be it known that T, Your 8. li-inur, a citizen of the United States. and a resident of the city of Chicago, in the county of Cook andHtate of Illinois. ha re invented certain new and useful lmmovements in Headlights; and T do lu-rreby declare that the following is a full. clear, and exact description oi the same. reference being had to the acrompalrving drawings, and to the numerals of reference marked thereon, which form a part of this specification.

The glaring headlights used on motor ars have proved to he. a source of considerable danger to drivers of other vehicles or motor ears approaching from an o 'iposite direction. owing to the fact that the intense beam oi light from the headlights momentarily blinds the OPL-"Xdtfll of the approaching vehicle. In a great man cities ordinances have been passed prohibitii'ig .the use oi? glaring headlights and consequently it has become necessary to provide a headlight which can be dimmed for use in cities where such' ordinances require and yet may, by slight adjustment, be made suitable for use upon .as open road in the country .or suburbs. Accordingly this invention relates to a means of attaclm'ient upon a headlight which acts to soften and diffuse the light tl'iercirom, distributing the. same over a wide area. for use in cities or other properly lighted places, and yet by detaelunent of said means said headlight becoming instantly useful for throwing a far-reaching and bright beam of light directly ahead upon the road in unfrcquentcd or poor]y.,lighted thoroughfares. The device not only permits the owner or operator of a motor car upon which such headlight is mounted to comply with the regulations governing the use of the same hut also adds greatly to the ornamental appearance of the light.

It is an object therefore of this invention to construct a headlight provided with means for attachment or detachment there from acting when attached to diffuse and distribute the light over a'wide area ontirely with art a glaring effect.

It is also an object of this invention to construct'a headlight provided with a glass or lens a part of which is clear, and a part of which is frosted, and with. removable means attachable over the clear portion acting to difluse the'intense rays of light which would otherwise be emitted therethrough.

It is also an im )ortant objectof this in mention to constrlut a headlight the glass or lens of which is provided with a frosted annulus leaving a ientral aperture of clear glass over which frosted auxiliaryor sec ondary lens may be attached, acting when so attached togetler with said frosted annulus to diffuse tl 9 light over a wide area, and when removed permitting an intern beam of lightto be thrown directly ahead. It is furthermore an important object of this invention to ronstruct a headlight pro-- rided with a flat main lens and a domeshaped auxiliary 1 ms attachable thereon, {lo latter when attached acting, together with said main lens, to diffuse the light over a. wide area entirely without glaring etl'oc and when removed permitting an intern-3e bealii or ray to is thrown directly ahead. said auxiliary lens being'curved or dome shaped.

It is finally an important object of this invention to construct a headlight whic for use in cities or other'places prohibitii the use of glaring lamps, may by simple at taelnnent of an auxiliary lens act to (llfllltithe rays of light over a wide area, and ye:

readily detachabh from the main lens when a strong and far reaching ray of light is i desired.

The invention in the preferred form) illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a ce atra-l vertical section tah through a headlight embodying theprin ples of my invention witlrparts shown in; elevation ji i Fig. 2*is a tr nt view thereof.

Fig. 3 is a vi .w similar to Fig. 2, but with the secondary or nixiliary lens detached.

Fig. 6 is a frtgmentary base view illustrating the means of attaching the auxiliar lens shown in Fig. 5. 1B5

Fig.7 is a vie-av similar ,to Fig. 5, of 217.;- other modified form of device. 7 Fig. 8 is a fragmentary face View thereof. As shown on the drawn The outer metal casing o the lamp is indi- 31c cated hythe reference numeral 1, and as usual is construt ted ofsheet metal formed conveniently to a parabolic shape, and having fitted within its edge a ring 2, which may be expanded thereinto or soldered as desired to afford a rigid connection. A parabolic reflector 3, is secured along its outer flat margin upon said ring 2, and is provided with a central aperture through which a receptacle 4, for any conventional bulb 5, extends. Said receptacle is held in position by means of an outer thumb nut 6, and an inner'nut 7, 'hich are engaged upon the stem of said receptacle and act to clamp the same securely upon said outer casing 1. \Vires for the bulb are inclosed in a lead 8, which is connected to a connection 9, secured in an aperture in the lower wall of the casing 1. The form of the glass or lens used in the headlight shown in Figs. 1,2, and 3, embraces a circular piece of glass having a frosted annulus portion 10, and offset outwardly and centrally therefrom is a circular clear portion of glass 11, the outer periphery of which has threads cast or formed therein as indicated by the reference numeral 12. A curved or dome shaped circular cap of glass'13, which may be frosted, colored, or opaque, as desired, or which of course may be of other material than glass, is secured within an ornamental metal ring 14, by means of an inner threaded ring 15, which is soldered to said outer ring 14, and is adapted to be threaded upon said threads 12, of the offset portion of. the main glass, thus maintaining, said cap 13, in osition.

The main lens of the hea light is held in position within-an outer ornamental metal ring 16, and an inner ring 17, of Z-section, which is soldered therein or otherwise socured thereto, said assembled rings 16 and 17, being attached to the main casing 1, of the lamp on each side thereof. For this purpose a pair of lugs 18 and 19, are riveted or brazed upon the exterior of said casing 1, one pair on each side thereof, and complemental lugs 20, are mounted on said ornamental ring 16, adapted to inter-fit between said respective lugs 18 and 19. All of said lugs are apertured to receive pintle bolts 21, therethrough which hold the same engaged with one another, thus maintaining the main glass or lens held rigidly disposed over the rout of the lamp. In the modification illustrated in Fig. 4,

' I have shown the attaching rings 1b and 17,

similar to those already described, but in the present instance the main light of glass consists of a single flat member having, however, an annulus 22, of frosted glass, and a circular clear portion 23 Cemented or affixed in any desired, manner upon said main light of glass surrounding the clear portion 23, thereof, is a threaded ring 24, preferably of metal, and a dome shaped glass cap 25, similar to the cap 13, already described, is adapted to be detachably secured over said clear glass portion 23, upon said ring 24, in a manner a ready described.

In Figs. 5 and (3, I have illustrated another modification wherein the main lightof glass which consists of a frosted annulus 26, and a clear central portion 27, has cemented thereon a metallic ring 28. A dome shaped glass cap, either frosted or colored as desired, is attached thereon by means of a split ring 29, which is provided with flanged or lug portions engaged by an adjustable bolt 30, for contracting the ring, thus holding said glass cap clamped upon the attaching ring 28.

In Figs. 7 and 8, I have illustrated another arrangement for attaching the cap 25, upon the main glass, and for this purpose one edge of a unitary metallic ring 31, is folded inwardly as indicated by the reference numcral 32, to afford a flat surface whereby the ring may be cemented upon the main glass. and a grooved outer portion 33, is provided, into which a split ring 34, may besprung over the flange of the cap 25, said split ring of course removable to permit detachn'ient of the cap.

\Vhen the headlight is used in cities or inother places where a non-glaring light is required, the dome shaped glass is attached upon the main light of glass orlamp of the headlight, it being a simple matter to attach and detach the glass upon the headlight in any Of course it is perfectly obvious that the cap may be also 'hingedly connected either directly to the attaching means upon the main light of glass or to the outer rings 16 and 17, so desired, so that said cap may then be 'tl nro'wn back into an open position.

The light has been found to be peculiarly efficient for use in the country and other open places where a strong bright light is required for the reason that with thesmall secondary cap removed, a beam or'ray of light is thrown far ahead, and the frosted annulus of the main glass acts to distribute other of the rays of the light over a wide area directly in front of the vehicle.

It is obvious that this invention is susceptible of wide variation without departing from the principles thereof, and I therc fore do not purpose limiting the' patent granted otherwise than necessitated by the prior art.
